Do you know why your club play in the colours that they do? My team, Millwall, play in blue and white because they were formed (in 1885) by a group of men that worked in a scottish owned jam factory based in London so they adopted the Scotland colours

Does that explain the jammy results? .... Only joking john, could be a good thread this one. I know man utd were newton heath, links with the railway, but I'm not sure about the colours though, it was green and yellow in them days, looked like budgies.... Lol, don't ask me how the red came about, I'm sure someone will google it.... Lol

Scarlet and blue have featured on the club shirt for more than one hundred years and the club is widely known as the ‘Blaugrana’ in reference to the names of these colours in the Catalan language.

It was claimed for several years that the Barça colours were adopted from a Swiss club that Gamper had founded earlier in his life, or that they were the colours of the Swiss canton that the founder was from. We now know that these hypotheses are highly unlikely to be true.

No ever managed to offer conclusive evidence of why it was that Barça used these colours from its very earliest days. But what can be sure is that the Barça shirt has gone on to be one of the most recognisable and enigmatic shirt designs in world football.

During its days as Newton Heath, the club played in a number of different colours, the most recognisable being the yellow and green halved shirts worn from 1878 to 1892, and then again between 1894 and 1896; this strip was revived as an away kit in the early 1990s. Other kits worn by Newton Heath included a red and white quartered shirt (1892–1894) and a plain white shirt (1896–1902), both worn with blue shorts. [37] In 1902, in conjunction with the name change to Manchester United, the club changed its colours to red jerseys, white shorts and black socks, which has become the standard for most Man Utd home kits ever since. The most notable exception to this is the shirt that the team wore in the 1909 FA Cup Final against Bristol City, which was white with a red "V" sash. [38] This design was resurrected in the 1920s before United reverted back to the all-red shirts, as well as for the home and away kits for the 2009–10 season to celebrate the club's 100th year at Old Trafford. [39][40]

Away strips are usually white jerseys with black shorts and white socks, but other colours have been used, including a blue and white striped shirt used on-and-off from 1903 to 1916, an all-black kit in 1994, 2003 and 2007 and a navy blue shirt with silver horizontal pinstripes in 2000. One of the most famous, yet short-lived, United away kits was the all grey kit from 1995–96, which was dropped after the team failed to win a single game while wearing it. At half-time during a game against Southampton, when United were already 3–0 down, they switched to their blue and white third kit, but eventually lost 3–1. According to the players the grey kit was not visible enough, which led to the poor results. [41][42] Another famous Man Utd away kit included a reversible shirt that was white with black sleeves and gold trim on one side, and gold with black trim on the other side. This shirt was released as the last kit created by Umbro for the club before the change to Nike, and commemorated 100 years since the club had changed its name from Newton Heath to Manchester United.

The United third kit is traditionally all-blue in homage to the kit that the 1968 European Cup was won in, direct reference to which was made with the club's 2008–09 third kit for the 40th anniversary of 1968. Exceptions to this rule have included a bright yellow kit worn in the early 1970s, the aforementioned blue and white striped shirt from 1996, which proved to be a firm favourite with the fans, and a white shirt with black and red horizontal pinstripes from 2004. United have also used what were originally used as training shirts as their third kit in the past, having adopted an all-black kit in the 1998–99 season and a dark blue shirt with maroon sides in 2001 for games against Southampton and PSV Eindhoven.

Currently, Manchester United's home jerseys are red with a shallow black chevron across the chest. The club crest sits on a black shield of the same shape on the left side of the V, while the Nike logo is in white on the right side; the AIG logo is also white. In recognition of the 100th anniversary of the opening of the club's Old Trafford stadium, a label reading "The Theatre of Dreams Since 1910" attached to the side seam. The home shirt is worn with white shorts with red stripes down the sides of both legs, and black socks with a red chevron on the calf. [39] The most recent away kit is in the same design as the home kit, but the shirt is black with a blue chevron on the chest and the club crest sits on a blue shield. Like the home kit, the sponsors' logos are both in white. The shorts are also black with blue stripes down the sides, while the socks are black with a blue chevron on the calf. [40] The club's 2008–09 away kit, consisting of a white shirt with blue stripes down the sides and a blue collar with red trim, is being used as the 2009–10 third kit. Worn with blue shorts and white socks, the third shirt has blue sponsor logos and the letters "mufc" on the back of the collar. The club badge sits on a white shield on the left breast. [43][44]

The Manchester United crest has been altered on a few occasions, but the basic form remains similar. The badge is derived from the crest of the city of Manchester. The devil on the club badge stems from the club's nickname "The Red Devils", which was adopted in the early 1960s after Matt Busby heard it in reference to the red-shirted Salford rugby league side. [45] By the end of the 1960s, the devil had started to be included on club programmes and scarves, before it was finally incorporated into the club badge in 1970, holding its unmistakable trident. In 1998, the badge was once again redesigned, this time removing the words "Football Club"

Did you know that it has been proven that teams that wear a predominatley red kit are more likely to win than a team that wears blue for example. This was scientifically proven, it is because red is an imposing colour and the opposition will coward away from it. Look at the big clubs, manchester united, Arsenal, Liverpool, Barcelona(sort of red), Roma, AC Milan. Even in the lower leagues you will find that the majority of the teams wearing red will be in the top half of the table.

Liverpool used to play in green and before that they used to play in grey aswell. I don't know why liverpool play in red though nowadays, can anyone tell me?
